CASE-FORMING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 549,498, dated November12, 1895.

Application filed October 12 1892.

To all whom, it may concern:

Be it known that I, THOMAS DEAN, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented new and useful Improvements in Case-Forming Apparatus, ofwhich the following is a specification.

My invention relates to new and useful improvements in machines for. themanufacture of book covers or cases; and it consists in mechanism forapplying the millboards and paper-stiifeners to the cloth covers andmeans and mechanism for trimming the corners of said cloth covers.

The object of my invention is to provide means whereby the machine canbe quickly and accurately set to operate on various sizes of covers orcases; to provide means for automatically conveying the cloth (which hasbeen previously cut to length and coated on one side with an adhesivesubstance) to the formingtable and holding it in position thereon whileapplying the millboards and paper-stiffeners thereto, and finallyremoving said partiallycompleted cover from the machine; and to providesuitable means whereby the corners of the cloth on the covers will betrimmed diagonally or at an angle of forty-five degrees, and forcompressing the millboards and paper-stiffeners to the adhesive surfaceof the cloth covers. I attain these objects by means of the mechanismillustrated in the accompanying drawings, in each of the figures ofwhich similar numbers of reference designate like parts.

Figure 1 is a plan of my machine, showing a portion of the adjustablestandards broken off, and showing a portion of the forming-table insection. (See Figs. 2, 3, and 6, line A B.) Fig. 2 is a sectional sideelevation of the machine through the line C D. (See Figs. 1 and 6.) Fig.3 is a side sectional elevation of the machine taken through the line EF, (see Figs. 1 and 6,) and showing the millboard feeding andapplyingmechanism. Fig. 4 is a detail end view of the push or feederhead for sliding the millboards .in position over the forming-table.Fig. 5 is a transverse detail sectional view of the receptacle forholding the paper-stiffeners in position over the center of theforming-table. Fig. 6 is a transverse sectional elevation of the machinethrough the lines G H I. (See Fig. 1.) Fig.

7 is a perspective view of the machine. Fig. 8 is a side elevation ofoneof the links of the traversing-chain, showing a grip formed thereonand in its open position. Fig. 9 is a group view of the grip, showingsaid grip-jaws in their closed position. Fig. 10- is a detailperspective view of the forming-table. Fig. 11 is a plan view of thelattice-work or lazytongs in their open or extended position, and Fig.12 is a similar view showing said latticework in its closed orcontracted position.

The machine is constructed with a main frame or sole-plate 1, whereonthe movable standards 1, 2, 3, and 4: are supported and are adapted toslide on the ways 5.

The end or outer standards 1 and 2 are operated to move simultaneouslyby means of the traversing-screws 6 and 7, positively connected bymeansof the shaft 8, and the bevelgears 9; and the center standards 3 and lare operated to slide on the center'portions of the ways 5 by means ofthe traversing-screws 10, connected to be operated simultaneously andpositively by the shaft 11 and the bevel-gears 12, secured thereon. Thismeans of adjustment of the standards is provided for the purpose offacilitating their adjustment to fit and to receive any of the varioussizes of millboards and paper-stiifeners required for a particular classand size of case or cover.

On the inner sides of the pairs of standards 1 and S, 2 and 4 are formedthe flanges or shelves 13,'which are provided for supporting themillboards which have been previously formed and cut to the proper size,and for maintaining them in position tobe'fed out singly, as required.

The horizontal flanges or shelves 13, which extend horizontally on eachof the standards 1, 2, 3, and 4, are of a sufficient depth and strengthto permit the T-ways 14 (see Fig. 3 and detail, Fig. 4) to be formedtherein andto extend throughout their entire length, and to receive thefeed-heads 15, which accurately fit and slide therein.

The push-gages 16 are adjnstably secured to the wings of thefeeder-heads 15 and project above the-top edge thereof a distanceslightly less than the thickness of the millboard to be used, for thepurpose ofsecuring the engagement of a single board at one stroke ofsaid head.

The heads are operated simultaneously by means of the rocking arms 17,having their forked ends 18 slotted longitudinally to receive thekeeper-pins 20, said pins passing through said slots 19 and tightly orneatly fitting in thelugs 21,formed on the bottom edges of the heads 15.

The rocking arms 17 are firmly secured on the shaft 22, journaled insuitable bearings 23, formed 011 the main frame 1, said rocking-shaftoperated by means of the crank-pin 2t, secured on the outer face of thedisks and connected by the connecting-rod 26, and the crank-lever 27,secured on the end of the shaft 22.

On the inner sides of the standards 1, 2, 3, and t are adjustablysecuredthe gage-strips 28, which I provide for the purpose of retaining thefront edges of the millboards in per feet alignment and position, andwhich have theirbottom ends raised slightly above the top horizontaledges of the shelves 1.3 to form an opening slightly is excess of thethickness of the millboard used, said opening not sufficiently great topermit the passing through of more than one of the boards from each ofthe holders for each stroke of the feeder-head 15.

The millboards are traversed horizontally or fed from their holders inpairs, out to and on the collapsible or hinged sup porting-wings 25),which are hinged 011 the inner sides of the standards 1, 2, 3, and 4,and are held in their horizontal positions by means of suitable springs(see detail Fig. 5) which are constructed with a tension sutficient tosustain the weight of the milling-board.

Intermediate between the central standards and -t are the paper-holders31, (see Figs. 2, 3, and 5,) which have their bottom edges flanged topass under and to support the paper-stiffeners and are provided with theV-guides 32, which are adapted to accurately fit and to slide in theirways 33, formed in the sides of said standards, said. holders held inposition nearer to the forming-table by means of the compression-springs34:, secured in said ways and engaging said Vs The follower-boards 35are suspended on the ends of the arms 36, which are firmly secured onthe rocking shaft 37 and operated by the rocking lever 38 (see dottedlines in Fig. 3, also perspective view, Fig. 7) and the connecting-rod39, working on the crank-pin secured on the face of the cam-disk 25.

1O designates the knives for trimming diagonally the corners of thecloth of the covers and are secured on their heads +11, said headsadjustably secured on the standards 1 and 2 and adapted to be moved inthe ways formed therein.

42 designates the bed of the forming-table provided with the verticaland parallel guiding standards 11, adapted to accurately fit and toslide longitudinally in the ways formed in the main frame 1 orbed-plate.

The top portion of the forming-table et3 is composed of a longitudinaland a transverse central portion and is provided with the adjustablecorner-pieces i5, which have their diagonal or mitered edges l6 formedintegral thereon, said corners moved simultaneously and adjusted ontheir ways 4E7, formed on the base or the bed 42 of the said table 43,by means of their traversing-screws 18, 4.), 50, and 51, operatedmanually by the shaft 52 and the bevel-gears 53, keyed on said shaft andscrews. (See Figs. 1 and 6.)

Intermediate between the movable 1n itered corners 4:6 and the centraltransverse portion of the operating or forming-table 43211-0 located thelattice-work or lazy-tongs 51 which I provide for the purpose ofsustaining the cloth from sagging, said cloth, being rendered pliable bythe application of its coating of glue, is incapable of sustaining itsown weight.

The bed 42 and its operating table are raised upwardly and downwardlyintermittently by means of the pins or cranks 55, secured on the endsofsaid bed of the formingtable and engaging the eamways 56, formed inthe face of the cam-disk 25.

The cams are firmly secured or keyed on the shaft 57, on the oppositeends thereof, the shaft being journaled in suitable bearings formed inthe main frame 1 and rotated by a suitable driving-pulley 58 by a beltin the usual manner. (See Fig. 6.)

59 designates the traversiilg-ehains, which are adapted to slide intheir ways 00, supported in any suitable manner to the permanent portionof the operating-table, and is driven by any suitable drive-chainmechanism. (Not shown in the drawings.)

To the chains 50, at intervals apart, are secured the gripping-clips(31, which are arranged to grip the ends of the cloth after re ceivingthe coating of glue and conveying said glued cloth in position on andover the forming-table. (See detail, Figs. 8 and 9.) The grippers ('31are operated to open bymeans of the inclined cam or trip formed on theguideways U0, contacting with the arm (51 to depress it and to open thejaws of the said grip 61. The arm 61 of the grip, when released from thetrip (50",permits the spring (31" to immediately operate to close thejaws 61 of the grips.

The type of chain used for the traversingchains in this machine andillustrated in the drawings is what is commonly termed the plate-and-pinchain, and is formed of a series of parallel plates loosely rivetedtogether to form hinged joints, and is different from the link-chainused in connection with sprocketwheels, the latter chain bein known asthe plain-link chain.

The adjustably-secured knives are illustrated in Fig. 6 and the newperspective view Fig. 7, and are designated in each of the figures bythe numeral 40.

02 designates the adj usting-gagcs of the paper-stiffeners, holder, orreceptacle, and is removably secured to the center standards 3 and 4 bythe securing-bolt (33. (See Fig. 2.)

The operation of my machine is as follows:

ITO

The standards 1, 2, 3 and 4 are previously set the proper distanceapartby the their traversing and adjusting screws 6 and 7 and the screws 10to receive the millboards, and the pap er-holder or pap er-stiffenersare built up or banked in their respective sections or holders, fromwhence they are automatically fed singly, as required, over the top andon the forming-table. The cloth having been previously coated with anadhesive substance,as glue, is gripped or caught by the grippers 61 andconveyed from the machine wherein the cloth is coated with adhesivematerial by the continuous conveyer-chain 59 to and on theformingtable,whereon it rests. The forming-table 43, whereon it lies asmall period of time, is now elevated by the simultaneously-acting cams25, till the adhesive surface of the cloth contacts with the millboardssuspended or resting on the supporting-shelves and till said adhesivesurface contacts with the lower paperstiffener supported in its holder.Simultaneously with this operation also operate the knives 40 todiagonally cut the corners of the cloth and the followers to press themillboards and paper-stiffeners firmly against the adhesive surface ofthe cloth. The followers 35 now ascend to their former position, thetable 43 descends, and the conveyer-chain removes the partially-workedcase from the machine to a suitable place where it is further operatedupon to finish the operation. Simultaneous with this latter movementanother set of milling-boards are fed in position over the forming-tableand another cloth of suitable size is conveyed on said forming-table tobe treated as before, and so on, continuously, the millboards and thecloth are fed to be operated upon.

Having thus fully described the operation and construction of myinvention, what I claim as new and useful, and desire to cover byLetters Patent of the United States therefor, is

1. In a machine for manufacturing covers or cases for books, thecombination with the main supporting frame thereof, a table havingdepending supporting standards adapted to slide vertically in suitableways formed in said frame, of continuous conveyer chains adapted totraverse along the parallel sides of said forming table, chain guideways having the cams or trips 61. formed on their inner surface engaginggrips composed of upper and lower hinged jaws and arranged at regularintervals along said chains, and projecting arms on the upper hingedjaws of said grips adapted to contact with said trips, substantially asand for the purpose set forth.
